Me and my girlfriend had a great 2 week stay at Tangmo's apartment which is conveniently close to Chatuchak park. It is on the 20th floor and has a nice view towards south Bangkok from the bedroom. All the kitchen amenities are there for doing your own cooking and there is a washing machine in the balcony area.
The gym and pool facilities at Sym Condominium were perfect and clean. Despite covid situation, there are some nice food options nearby during the day and even a cheap food court opposite the building. Good proximity to either BTS or MRT stations.
This place is perfect for a mid to long stay outside of the busier Bangkok areas. Would happily stay again!
